Autodesk offers almost all its software free to students. This includes AutoCAD, Fusion 360, Inventor, Maya and Revit. The site http://www.autodesk.com/education/free-software/all has a list of the software with links and instructions for the free student license.
Autodesk also makes 123D Make which converts 3D objects to 2D plans. The site includes links to download for PC, Mac, and iPad/iPhone, but the app has disappeared from the Apple Store.
Solidworks Student Engineering Kit (SEK) is free for all CMU students and affiliates. You can purchase the disks from the CMU Computer Store for $25.00. Note that you are purchasing the physical media, not the license.
So that you don’t have to buy them, we have made available the disk images for Solidworks SEK 2017–2018 in ISO format for Windows 10, 8.1, and 7 SP1. The files are shareable to any CMU affiliate via Box, so you can give the link to any CMU student who wants to download the files; the serial number is in the README file:
Note: The disk files are large, and you will want at least 50 GB of free disk space for the installation process. You probably only need the first of the two disks for a standard installation. If you are running Windows 7, you’ll also need a program like WinCDEmu to mount the ISO files.
Ansys provides a free license to students for special versions of its software simulation packages. The following blurbs are extracted from their descriptions of the packages:
